Node-level Performance Engineering, 15-16 May 2014

CSCS organized May 15-17 a 2-day training course aimed to teach performance engineering approaches on the compute node level. "Performance engineering" is intended as developing a thorough understanding of the interactions between software and hardware. The instructors were Prof. Gerhard Wellen and Dr. Georg Hager from RRZE, Germany.
